"The operation went perfectly, which is the most important thing for now. We and our captain are now looking to the future. Manuel will be back to his previous best and available to us again in January."

Bayern, Bundesliga champions for the past five seasons, have taken nine points from their first four games and face Schalke 04 away later on Tuesday.

Zidane confirms Real Madrid contract renewal

Real Madrid coach Zinedine Zidane said that he has renewed his contract with the Spanish champions, although the deal has not yet been announced officially.

Madrid have renewed various players' contracts in recent weeks and the Frenchman told a news conference that he too has extended his deal, which was set to expire at the end of this season.

"In terms of the renewal, it's already done, but it doesn't mean anything," said Zidane.

"I care about the day to day and I'm not looking further than that, this is complicated."

Zidane took charge of Real in January 2016 and has led them to consecutive Champions League trophies and their first La Liga title since 2012, as well winning the UEFA Super Cup twice and the FIFA Club World Cup.

Real Madrid continue their league title defence on Wednesday as they host Real Betis, although they will be without defender Theo Hernandez who injured his shoulder in Sunday's 3-1 win at Real Sociedad.

"He has been diagnosed with a partial dislocation of the right shoulder," Madrid said in a statement on Tuesday, with Spanish reports indicating Hernandez will be out for a fortnight.

Arsenal's Welbeck to be out for three weeks with groin injury

Arsenal's Danny Welbeck is out for at least three weeks with a groin injury and manager Arsene Wenger said that the striker is unlikely to return before next month's international break.

Welbeck was hurt in Arsenal's 0-0 draw at Chelsea on Sunday and will miss Wednesday's League Cup match against third tier side Doncaster, Premier League games with West Bromwich Albion and Brighton & Hove Albion, and a Europa League fixture against Bate Borisov.

"Danny has a scan today, we don't know how bad his groin injury is but he will certainly be out until the international break," Wenger told the club's website.

The 26-year-old, who has scored three times for his club this season, is also unlikely to feature for England in their upcoming World Cup qualifiers against Slovenia on Oct. 5 and Lithuania on Oct. 8, though he could return in time for Arsenal's trip to Watford on Oct. 14.
